The README opens with
Coding agents break your rules from the very first edit. oh-my-plumb catches every one and makes your agent fix it
1 in 13 turns break a rule no linter can catch · oh-my-plumb does · 0.4 to 1.3 s per check · a tenth of a cent per turn Measured by replaying 93 real Claude Code sessions (1,256 edits, 147 turns) in two repos against their own AGENTS.md, for 22 cents. Jev flagged 39 edits and 15 turns; an independent reviewer confirmed 10 and 11. The turn-level catches (single-use abstractions, oversized files, duplicated logic) held up 11 times in 15. Method, per-rule table and what was wrong: benchmarks/replay .
